If he wins 9 this year that would be an impressive feat IMO and would go a long way with the non-believers. 8 wins would be meh but enough to keep him around to see what he does without a 4 year starter at QB. Anything less than 8 show him the door, no apologies no excuses.
For that 9 wins to happen, there can't be much of a dropoff on D, and the O has to be a whole lot better, starting with the OL. A couple of pretty tall orders. That O had beeter figure out a way to get the ball in the end zone a lot more than it has the past few years.
As usual with Pitt football of the past 30 years, the smart play is to keep your expectations low and hope to have them exceeded.
As for the Krull "looking like a first rounder" comment, we've all heard that kind of thing from the Dooz many times before. Doesn't mean a thing until the games are played.
